Enhancing N2-Fixing Symbioses for Sustainable Agriculture

This research focuses on plant-microbe interactions, particularly involving root nodule bacteria (rhizobia) and their unique ability to convert atmospheric nitrogen (N2) into a form usable by plants. The study aims to improve nitrogen-fixing efficiency in agricultural systems, reducing the reliance on chemical fertilizers and the carbon footprint of farming. Key research objectives include understanding the determinants of N2-fixation efficiency, identifying genetic factors influencing symbiotic effectiveness, and exploring strategies for selective nodulation in crops like Medicago truncatula.

  1. Honours Projects 2013Jason Terpolilli • I am part of the Centre for Rhizobium Studies in the School of Veterinary and Life Sciences (please note our new website is under construction) • My research focus is in plant-microbe interactions, and the root nodule bacteria • RNB (rhizobia) are unique in their ability to convert atmospheric N2 into plant-available N in symbiosis with legumes • Research in the area is driven by: • Requirements for highly efficient N2-fixing symbioses in agriculture, which reduce CO2-footprint of farming and reliance on chemical fertilisers • The integral place N2-fixation plays in nutrient cycling. • On the next few slides are some potential honours projects. If any of them interest you, or you have any questions about them, I encourage you to come and discuss them with me. Cheers Jason J.Terpolilli@murdoch.edu.au
